Hello Coco, I feel less alone too reading your post, as sad as it made me that someone else knows what this feels like.
I'm only taking Prozac at the moment but might ask for some emergency meds like Diazepam for the worst panic attacks. I also have my first assessment for CBT this week on Wednesday. I'm very nervous but sort of excited at the same time.
Re. the praying, I was driven to prayer despite being agnostic at best throughout my teenage years. I don't know why, I was so desperate I was willing to try anything. I'm at university so my family worry endlessly about the impact the OCD has on my time there. As much as I love to I can't go out to crowded places much, and I can't drink. But you have your friends and family as I do and you must use their support. Talk to them constantly they will understand.
At my lowest, I didn't want to live my life with these thoughts. I stood at the end of a pier and thought about suicide, a way in which I could make it look accidental to not hurt anyone's feelings. That's how bad it got while I felt alone and was unaware of OCD. But we have an illness. Here's some books that may help you:
Brain Lock - Jeffery Schwartz (About £6)
Overcoming Obsessive Compulsive Disorder - David Veale &...someone else, (About £7)
Break Free From OCD - Challacombe, Oldfield and Salikovskis (About £9)
All of them are brilliant. If you still don't think the thoughts are related to a condition in your brain and aren't dangerous, take some online OCD tests. List your compulsions, it was only when I did this that I realised that I really do have bad OCD. (Though, if you don't have many, remember pure O).
Here's an image as to why you have intrusive thoughts that just won't go away, this PET scan shows the difference between us and those without OCD:

You need medication or treatment specifically for your depression as I've said to someone else on here today, as the depression might impact your ability to undergo CBT. That's why I haven't been able to start yet. Concentrate on beating this first. Remember you have a condition and you are totally harmless. Keep busy too, find a hobby or activity however small that can fully occupy your mind. Mine was video games and walking, without which I wouldn't have got through the period I was waiting for the intrusive thoughts to subside.
Please read some material on OCD and message me at any time if you're feeling anxious. I'll get back to you as quickly as I can.
